29. ANALYTICAL APPROACH TO SEISMIC BEHAVIOUR ASSESMENT OF RC FRAME STRUCTURES WITH RUBBER JOINTED MASONRY INFILL

Liljana Bozinovska Mijalkova

PhD special session

Extended abstract

Infilled structures are the most used type of structures in seismic-prone countries. Masonry infills are the most vulnerable part of these structures, even under medium-intensity earthquakes; hence, developing systems to prevent their failure to protect goods and human lives is crucial. Since current design codes are very advanced in reinforced concrete structures designs and there has been...

38. Effect of base column rotational stiffness on the seismic response of steel framed buildings

Menelaos Papamichelakis (Hellenic Open University, Laboratory of Applied Mechanics and Structural Technology)

PhD special session

Full paper - scientific

This paper examines the impact of what is arguably the most critical connection in a steel building: the column base connections under earthquake loads. Failure of this connection can lead to partial or even complete structural collapse. The rotational stiffness of these connections—whether they are considered fixed or pinned—significantly influences the seismic response of steel buildings....

22. Influence of Ground Motion Record Selection on Higher Modes: A Comparison of UHS and CS Approaches

Jose Poveda (IUSS Pavia)

PhD special session

Full paper - scientific

This study examines the influence of code-prescribed methodologies for ground motion record selection on the higher-mode response of structures. Specifically, it compares two conceptually different target spectra: the Uniform Hazard Spectrum (UHS) and the Conditional Spectrum (CS). Using shear wall buildings designed following Eurocode 8 (EC8) response spectrum analysis, we analyse the...

49. NATURAL COMPOSITES IN CONSTRUCTION: OVERVIEW OF THE DEVELOPMENT, APPLICATION AND CHALLENGES OF NATURAL FIBER REINFORCED CEMENTITIOUS MATRIX (NFRCM)

Mario Žigo (University of Split, Faculty of Civil Engineering, Architecture and Geodesy)

PhD special session

Full paper - scientific

Technological development in construction has brought significant advances in the application of materials, particularly composites such as fiber-reinforced polymers (FRP) and textile-reinforced concrete (TRC). These materials have become widely used due to their excellent mechanical properties, including high strength and low weight, making them suitable for the refurbishment of damaged...

86. NEAR-DISTANCE SPECTRAL PARAMETER KAPPA CALCULATIONS FOR STATIONS INSTALLED IN N. MACEDONIA

Marina Poposka (Ss. Cyril and Methodius University in Skopje, Institute of Earthquake Engineering and Engineering Seismology, Skopje, R. N. Macedonia)

PhD special session

Full paper - scientific

The objective of this study is to estimate the high-frequency decay parameter – kappa (κ) for stations installed on rock (according to EC8) for North Macedonia region.
Kappa characterizes the attenuation of ground motion at high frequencies, more precisely defines the rate of decrease of the acceleration amplitude spectrum. At higher frequencies ground motions on rock may be larger than...

46. Response of the building in aggregates according to the interconected different parameters

Maja Mrkonjic (Građevinski fakultet Sveučilišta u Zagrebu)

PhD special session

Extended abstract

On March 22, 2020, the capital of Croatia, Zagreb, was struck by a devastating earthquake that caused damage to many buildings. The most affected were the structures in the city center, constructed as buildings in aggregates, which are characterized by their architectural style and construction methods typical of urban environments from the Austro-Hungarian Monarchy period of the 19th century....
